Abstract: 818,933. Moulding. GENERAL ELECTRIC CO. Ltd. Aug. 14, 1957 [Aug. 24, 1956], No. 26005/56. Class 87(2). An article, e.g. a buffer block 5 for an electromagnetic relay, is made with a plurality of holes 3, 4 which are each formed during moulding in one or other of at least two surface portions of the article, the holes 3, 4 interconnecting within the article to provide an aperture that extends at least part of the way through the article and substantially at right angles to the axes of the holes 3, 4 the arrangement being such that adjacent portions of the length of the aperture are provided by the holes formed in different ones of the said surface portions. As shown, a through aperture for a fixing bolt 8 is formed in the buffer block 5 by the overlapping portions 15, 16 of core members 13, 14 projecting from and fixed to parts 11, 12 respectively of the mould, If the ends of the core members 13, 14 are flat as shown the transverse aperture is rectangular in section. By making them part-cylindrical the apertures approximate to a circle or ellipse. The core members themselves are rectangular in section, as shown, but may be triangular. The portions of the article in which the holes 3, 4 are formed may be planar or curved surfaces. In the moulding operation a charge of thermoplastic or thermosetting material may be introduced before or after closing the mould.

Title: Colour pickup tubes and method of manufacturing the same
IPC: H01J31/46
Filed: 1975-06-19
Abstract: 1482830 Image pick up tubes HITACHI Ltd 19 June 1975 [21 June 1974] 26054/75 Heading H1D A colour pick up tube has a transparent faceplate substrate 14, a photo-electric target (not shown) on its inner surface and metal terminals 20a, 20b, 20c, for the output signals, the terminals extending through perforations in the substrate to which they are secured and with one end of each terminal located below the inner substrate surface to form a recess. The arrangement facilitates mask positioning prior to photoresist exposure in the production of stripe shaped filters (16a, 16b, 16c) (Fig. 2, not shown) and conductive films (17a, 17b, 17c) connected by bus-bars (19a, 196, 19c). The recesses may be formed by chemical or electrolytic etching of the terminals, examples of these processes being included, or the terminals may be inserted of a length less than the substrate thickness. In Fig. 9 (not shown), the terminals are interposed between a separated portion and the remaining portion of the substrate and embedded in acrylic, polyimide or epoxy resin, or frit glass 94 for example. The arrangement of Fig. 4 for example eliminates non-uniform polishing due to differences in hardness of substrate and terminals, and scratching. Polishing details are included. After insertion of the terminals, a binder 26 such as polyimide, acrylic, or epoxy resin is poured in (Fig. 5A, not shown). The terminals may be KOVAR (Registered Trade Mark), Fe-Ni-Cr alloys, W or Mo. In Fig. 6 (not shown), bus-bar (19a) is connected to terminal (20a) by material (61) which undergoes plastic deformation at normal temperatures (e.g. Al and In), and is applied by pressing, vapour deposition or coating. Projection at the outside (Fig. 7, not shown) facilitates positioning, and as in Fig. 8 (not shown) one side may be flush and the other recessed. The transparent conductive film may be continuous rather than sectioned as in Fig. 2 (not shown) and an index screen disposed close to the photo-electric target for providing the output signals. The photoconductive layer 19 is included in Fig. 1 (not shown). Reference is made to photoconductive films constituting sections of the target mounted on the conductive films.

Title: Improved manufacture of ceramic products
IPC: C04B33/13
Filed: 1923-10-24
Abstract: 228,233. Vershofen, W. Oct. 24, 1923. Clay, porcelain, and like plastic compositions.- In producing ceramic ware by partially converting the clay into a cement by the addition of carbonate of lime, fluoride compounds soluble in water are usually added to start the chemical action. According to the present invention, silica is first added to clays in which the reaction with the fluoride is weak. The moulded articles are first air dried and then baked at a low heat, for example under 1000‹ C. Suitable proportions may be 30 per cent alumina, 5 per cent sodium fluoride, 60 per cent quartz, and about 5 per cent carbonate of lime. Higher percentages of fluoride produce a non-separable glazed surface; by adding calcium salts to the charge, the complete vitrification of the baked product by the fluoride is prevented and the clay bakes white and free from iron spots.
